Integrable models and degenerate horizons in two-dimensional gravity
J. Cruz, A. Fabbri, D. J. Navarro +1
We analyse an integrable model of two-dimensional gravity which can be reduced to a pair of Liouville fields in conformal gauge. Its general solution represents a pair of ``mirror'…
Can conformal Transformations change the fate of 2D black holes?
J. Cruz, A. Fabbri, J. Navarro-Salas
By using a classical Liouville-type model of two dimensional dilaton gravity we show that the one-loop theory implies that the fate of a black hole depends on the conformal frame.…
Hidden conformal symmetry of a massive scalar field in 2-dimensional Anti-De Sitter space
J. Cruz
We show that a massive scalar field on a 2-dimensional Anti-De Sitter space can be mapped by means of a time-dependent canonical transformation into a massless free field theory wh…
General Covariance and Free Fields in Two Dimensions
J. Cruz, D. J. Navarro, J. Navarro-Salas
We investigate the canonical equivalence of a matter-coupled 2D dilaton gravity theory defined by the action functional $S = \int d^2x \sqrt{-g} (Rϕ+ V(ϕ) - 1/2 H(ϕ) (\nablaf)^2)$,…
Canonical Equivalence of a Generic 2D Dilaton Gravity Model and a Bosonic String Theory
J. Cruz, J. Navarro-Salas
We show that a canonical tranformation converts, up to a boundary term, a generic 2d dilaton gravity model into a bosonic string theory with a Minkowskian target space.
Free fields via canonical transformations of matter-coupled 2D dilaton gravity models
J. Cruz, J. M. Izquierdo, D. J. Navarro +1
It is shown that the 1+1-dimensional matter-coupled Jackiw-Teitelboim model and the model with an exponential potential can be converted by means of appropriate canonical transform…
